Ectofly etc and shearing.

[Cab-over Pete]

Aye-up,

We often get a strike in April as the weather warms up and I want to avoid that this time.

We usually shear late April early May but I’m wondering if we shear a bit later and treat the ewes any time soon with something to prevent any early strike. I don’t even know if that’s possible re any kind of withdrawal times.

If we treat soon when is the earliest we can shear? How many weeks after treatment do we need to leave it. I’m only thinking something cheap and cheerful, then a long acting Clik maybe three weeks after shearing.

Cheers, Pete.

I do my adults with Clikzin about mid-April ..... Shear them 8 weeks later . It'll tell you on the safety factor on data blurb for the product .

We do something similar here. Also give ewes ( and lambs) a spot on type treatment at turnout to stop the ticks. Have thought about using Dysect on the ewes to do both jobs but haven't looked into wether it would be safe for the shearers several weeks down the line.

Basically the day I do them , I notify my local shearer so he has a plan in book . Works well here . Got 2 Clik guns here , and all lambs are done with Clik Extra on same day . With born late March>April , there's no hassle on withdrawals when ready to sell . When that runs out , I dob lambs with Clikzin . Ewes get reverse with Clik Extra , about 2-3 weeks post-shearing . Not cheap , but micro-climate here necessitates policy and I sleep nights !! Had a mega issue 1st week May years ago with 7 'clean' sheep struck .... Vowed that it would never happen again , as mega welfare issue .... Fortunately most folk take their chances or I wouldn't get my shearer on approx planned date ....

I always reckon at least 8 weeks, although Clik and Clik extra stipulates 3 month withdrawal for shearing.

I’m trying to work out which products I’m going to use this summer, but I’m ideally not wanting to cover ewes and lambs with the same ai for the whole summer. I’ve heard of resistance to some products and that would accelerate the issue

 

[Cab-over Pete]

Ok, thanks all, I’ll look into it.

Last thing I want to do is upset the shearer!

 

[andybk]

i shear my own and wouldnt want to be shearing through ANY chemical on a daily basis , its hard enough and low paid as it is .
anyone heard any news about generic click , was a lot of talk about it last autumn when irish bought up the old patent ,

 

[Romney_Rob]

We have the same problems so we put dysect on them last week in March, lamb them in April and then shear first week in June - it does seem to work well in keeping flies off. Although you wouldn't want to shear much later.

Critical bit is assessing strike likelihood . Did flock 21/4 last year as it was warm and muggy here . Was a week later the year before .

We have seen alot of resistance to these pour ons over the last couple of seasons.

 

[Filthyfarmer]

For the last couple of years sprayed 20ml crovect from shoulder to rump when ewes are crutched out in April, shear mid june so about 8 weeks. Good results.
Used to get quite a lot of strike on shoulders especially in muggy weather.

@The sheep dipper man ---you got a link to any of this data?
The only bit i can find is Aussi claims to Diazinon (OP) resistance ?
Might be a different story here of course?

There is no resistance been found in Diazinon over here or Europe.
Ill find some info for you and post it on here.

Waiting to get some info for you . I spoke to my dip manufacturer and they have said they are unaware of any resistance at all in any country to Diazinon!

@The sheep dipper man ---here's the link to the Aussi Flyboss site that mentions resistance to Diazinon

Choosing The Right Chemical For FlyStrike

Chemicals can be used strategically to reduce the risk of flystrike, this page provides information on the different classes of chemicals that are available for both preventing and treating flystrike.

Thanks ill have a read

 

[The sheep dipper man]

Thanks ill have a read

Interesting, i can only imagine that they have found resistance due to the use of jetters and showers over there!!.

It dose only talk about flystrike resistance and nothing about lice resistance, i know they dont have scab over there.

I dip 10s of thousands of sheep every year and have never had any issues with OPs not working.
We have no resistance to OP over here in the UK and Europe against any parasites. This is the reason why jetters and showers are illegal over here, if they are carried on being used there could be a possible issue in the future, if that did happen then we are stuffed !!!

Cant seem to get ot posted on here for some reason but what it say is ,
Data shows that the majority of ‘treatment failures’ are not the product but incorrect process or method of treatment use.

That's not resistance, then?


But, the nature of the product/chemical surely through improper application /treatment it is only a matter of time before resistance to the Clik products is found?... imo
